For the past couple of weeks, I have been running FC and TC levels between 3 and 7, with a CC level always 0. The pH runs between 7.4 and 8.0. I add 10% bleach and 14% muriatic acid each evening, the exact amounts depending upon the actual numbers. On Mondays I run full sets of numbers.
On 4/3, however, the FC dropped all the way down to 1.5 (checked twice), the TC was 3, and CC = 1.5. The TA was 60, CH 400, CYA was 50, and temp was 74F. I was supposed to add 406 oz. of 6% bleach, but only had 328 oz., so I added that. I also added 46 oz. of 14% muriatic acid and, for the first time, added 2# of baking soda to raise the TA.
I ran the pump all night & tested again first thing in the AM on 4/4. I got:
FC = 3
TC = 5
CC = 2
pH = 8.0
TA = 70
I ran out for more bleach and came home with 10%. I added 158 oz. of the 10% plus 51 oz. of 14% muriatic acid and kept the pumps on.
Last night I tested again and got:
FC = 25
TC = 25
CC = 0
pH = 7.4
TA = 70
CYA = 60
CH = 40 (!)
Temp: 74
I didn't touch the CH because it was such an erroneous reading from the 400-ish I usually get and figured I would wait and run it again tonight. Tonight's #'s are:
FC = 3 (after diluting. Had been off the charts, beyond 8. How could it only be 3 then??)
TC = 5 (using the diluted specimen)
CC = 2 (same specimen)
pH = 8.0 (probably higher)
TA = 70
CYA = 50
CH = 450
Temp = 74
Appearance: remains crystal clear
I am very confused now :? . If anyone could explain why these numbers are so baffling to me and what to do about it before I make more of a mess, I would be very appreciative. Thanks in advance.
